A waveform display is a visual representation of an audio signal's amplitude over time. It shows how sound waves fluctuate, allowing users to see the dynamics of the audio, such as volume changes and frequency content. This type of display is commonly used in audio editing software and digital audio workstations (DAWs) to help sound engineers and musicians analyze and manipulate sound. Waveform displays can also be found in various applications, including oscilloscopes for electrical signals and music production tools. By observing the waveform, users can identify specific features like peaks, troughs, and silence, which aids in tasks like mixing, mastering, and sound design.
